I don't believe in spirits or aliens. I follow science and evidence. But one funny thing I've noticed is with UFO and spirit encounters experienced by so called "hunters" of these things is that when confronted with actual evidence they get scared and run away. More so with spirits than aliens.
I don't know about you but if I'm confronted with a spirit or alien I'm gonna be quite interested and asking questions and observing everything and not running away like a scared little bitch.
